Description

Technical Field

[0001] The present invention belongs to the technical field of portable anti-animal protective gear that is excellent in portability and can protect a person when attacked by large wild animals such as bears.

Background Art

[0002] Recently, the damage caused by bears attacking humans (bear damage) has been increasing year by year.

Table 1

[0003] The problem with bear damage is not only that the number of damage cases and the number of victims are increasing, but also that the area where the damage used to occur only in the mountains has expanded into populated areas, and the damage in daily living areas (for example, near houses and public facilities, indoors, etc.) is increasing.

[0004] Regarding the content of the damage, there are many cases of serious injuries and deaths such as "bite wounds to the face and head" and "lacerations caused by scratching to the body and thighs", and the situation is very serious.

[0005] Conventionally, as devices for dealing with bear attacks, for example, a portable bird and animal repellent device that generates sounds from the audible range to the ultrasonic range (Patent Document 1); an electric shock device that injects a conductive liquid and applies a high voltage to the conductive liquid (Patent Document 2); a protective gear that injects a chemical solution (Patent Document 3); a portable wild animal repellent device that projects images and generates sounds (Patent Document 4); a protective gear that has a function as a striking weapon in addition to injecting a spray (Patent Document 5); etc. have been proposed.

[0007] However, these technologies had the following problems. First, these technologies were primarily intended to deter animals, and there were no means of defense in case the animal (especially large wild animals such as bears) attacked even after being deterred (Patent Documents 1 to 5).

[0008] Some devices have been proposed to attack animals (Patent Documents 2, 3, 5), but there are doubts as to whether a user who is in a panic when attacked by an animal can instantly launch an attack. Furthermore, if the attack is unsuccessful, the animal is likely to retaliate, so these devices cannot be used as a means of defense against animal attacks.

[0009] Furthermore, some devices are not necessarily portable (Patent Documents 3, 5). Considering that bear attacks occur in everyday life, carrying such large devices at all times is not a realistic defense measure.

[0010] This invention was made to solve the aforementioned technical problem of the prior art, namely, the lack of a portable means of defense for protecting oneself when attacked by an animal.

[0011] In other words, the present invention provides a portable animal-repellent device that is highly portable and can serve as a means of defense that instantly protects oneself when attacked by an animal. [Means for solving the problem]

[Figure 8] Figure 7 is a schematic diagram illustrating how to use the manifold shown. [Figure 9] This is a conceptual diagram showing another embodiment of the portable animal protection device of the present invention. [Modes for carrying out the invention]

[0018] The embodiments for carrying out the present invention will be described in more detail below. However, the embodiments shown below represent only a part of the embodiments of the present invention, and the present invention is not limited to the embodiments shown below.

[0019] [1] Features of the present invention: The present invention provides a portable animal-repellent device for protecting the user when attacked by a wild animal. It is characterized by: 1) comprising a gas supply source that generates gas, a plurality of airtight tubes into which the gas is injected and extended, and a protective sheet stretched by the plurality of airtight tubes; and 2) extending the plurality of airtight tubes with the gas generated from the gas supply source to form a skeleton, stretching the protective sheet with the skeleton, and forming a physical protective wall between the wild animal and the user.

[0020] The portable animal protection device of the present invention forms a protective wall by injecting gas into an airtight tube, which then expands as a framework, and stretching a protective sheet between these frameworks. Rather than inflating the entire protective wall, only the thin tube is inflated to form the framework, and a structure is adopted in which a strong protective sheet is stretched over this framework.

[0021] Because the structure inflates only a small volume of airtight tube (the skeletal part), it requires significantly less gas compared to a structure that inflates the entire protective wall. For example, even a small gas cylinder of about 45g (approximately 25L) can instantly form a strong protective wall large enough to cover a human body.

[0022] Furthermore, by using cut-resistant materials for the protective sheet that forms the protective barrier, attacks from sharp claws and teeth of bears and other animals can be physically blocked, ensuring the user's safety. In addition, since the airtight tube and protective sheet can be made of resin, they can be folded and stored compactly when not in use, making them suitable for carrying during outdoor activities.

[0023] [2] Portable animal protection equipment: The portable animal protection device of the present invention will be described below with reference to the drawings as appropriate.

[0024] The portable animal protection device 1 shown in Figures 1 to 4 is a device for protecting the user when attacked by a wild animal. While there are no particular limitations on the type of wild animal, it is particularly suitable for use as protection against large wild animals, especially bears, which have recently seen a dramatic increase in attacks.

[0025] One way to protect the user is to create a physical barrier (protective wall) between them and the wild animal to defend against its attacks. For example, in the case of a bear, attacks include biting with its fangs and scratching with its claws, and a single attack can often be fatal. Methods such as intimidating or attacking a bear with the body exposed, as in conventional technology, are extremely dangerous. The portable animal protection device of the present invention creates distance between the user and the wild animal with a protective wall, effectively preventing attacks from the wild animal from directly reaching the user's body.

[0026] The portable animal protection device 1 comprises a gas supply source 2, a trigger 4, multiple airtight tubes 6, and a protective sheet 8.

[0027] [2-1] Gas supply source: The gas supply source is a component that generates gas. This could be a system that stores gas in a compressed state, or it could generate gas through a chemical reaction. For example, a gas cylinder filled with high-pressure gas can be used. The type of gas is not particularly limited, but CO2 gas is one example.

[0028] The portable animal protection device 1 uses a 45g CO2 gas cartridge as the gas supply source 2. Because the portable animal protection device 1 has a structure in which gas is filled into a small volume airtight tube 6 and inflated, even a small gas cartridge is sufficient for it to function. Therefore, if one or two 45g or 33g CO2 gas cartridges are provided, a protective wall can be deployed, making it a highly portable animal protection device.

[0029] [2-2] Trigger: A trigger is a component that instructs the user to supply gas from a gas source. For example, it is a mechanism that, through user action (e.g., pulling a string, pressing a button, turning a lever), instructs the user to open the sealing plate of the gas source and start supplying gas, or to trigger a chemical reaction that generates gas. It may also be equipped with a safety pin or the like to prevent accidental operation.

[0030] As shown in Figure 5, the portable animal protection device 1 uses a regulator as the trigger 4. The trigger 4 (regulator) is connected to the gas supply source 2 (gas cartridge). This regulator signals the start of gas supply by rotating a lever. The illustrated trigger 4 is a type of regulator to which a gas cartridge can be connected and the gas cartridge can be replaced. Such regulators are commercially available and can be suitably used as triggers.

[0031] [2-3] Airtight tube: An airtight tube is a tubular component that expands when gas is injected into it. When gas is injected, the airtight tube expands into a rod-like or arch-like shape, forming the framework of a protective wall. For example, an airtight tube may be made of a highly flexible material and can be folded for compact storage. The end of the tube is equipped with a joint for connecting to a trigger. The airtight tube can be inflated by supplying gas from a gas source.

[0032] The material is not particularly limited as long as it is highly airtight and can withstand gas pressure. Considering the need to fold and store it compactly, a highly flexible material is preferable. For example, TPU (thermoplastic polyurethane) laminated nylon can be suitably used. TPU laminated nylon is made by laminating TPU onto a nylon base fabric.

[0033] The portable animal protection device of the present invention is equipped with multiple airtight tubes. This is to enable the uniform and rapid deployment of the protective wall. The number of airtight tubes is not particularly limited as long as such an effect is achieved, but when deploying a dome-shaped protective wall as described later, it is preferable to have about 6 to 8 airtight tubes. By arranging about 6 to 8 airtight tubes evenly on the inner surface of the dome-shaped protective sheet in a radial pattern from the center of the dome toward the outer edge, an umbrella-rib-like framework can be formed.

[0034] If multiple airtight tubes are provided, it is preferable to further provide a manifold having multiple gas outlets. The gas supply source is connected to the manifold via the trigger, and the multiple gas outlets of the manifold are each connected to the multiple airtight tubes, thereby allowing the gas supplied from the gas supply source to be distributed from the manifold to the multiple airtight tubes. The material of the manifold is not particularly limited as long as it is a material that has sufficient strength to withstand gas pressure and use as protective equipment. For example, metal (aluminum, etc.); hard resin (plastic, etc.) can be suitably used.

[0035] The manifold 10 shown in Figure 7 utilizes a donut-shaped hollow tube 10A and has a gas inlet 10B protruding from the center of the ring and eight gas outlets 10C protruding further outward from the outer circumference of the ring. As shown in Figure 8, a gas supply source 2 (gas cartridge) is connected to the gas inlet 10B via a trigger 4 (regulator), and eight airtight tubes 6 are connected to the gas outlets 10C. As a result, the gas from the gas supply source 2 is distributed to the eight airtight tubes 6 via the trigger 4 and the manifold 10.

[0036] A preferred embodiment is one in which the manifold 10 is structured to supply gas to all airtight tubes 6 substantially simultaneously. With such a structure, gas can be injected immediately and evenly into all airtight tubes 6, and a dome-shaped (umbrella-shaped) protective wall can be deployed in an extremely short time of 0.5 to 1.5 seconds.

[0037] The airtight tube is positioned on the back side of the protective sheet and is integrally connected to the protective sheet. This structure allows the airtight tube to extend when gas is injected, stretching the protective sheet and deploying the protective membrane.

[0038] The method for integrally joining the airtight tube to the protective sheet is not particularly limited, but examples include joining the airtight tube to the back surface of the protective sheet by heat fusion (welding); or inserting the airtight tube into a sleeve (sleeve-shaped member) attached to the back surface of the protective sheet.

[0039] (1) Method of joining airtight tubes by heat welding: For example, an airtight tube with a TPU coating on its surface can be used, and the airtight tube can be heat-welded to the back of the protective sheet to create a unified structure.

[0040] (2) Method of inserting an airtight tube into the sleeve: A sleeve for inserting a tube is attached to the back side of the protective sheet by sewing or welding. An airtight tube 6 is inserted into this sleeve, integrating the protective sheet and the airtight tube.

[0041] [2-4] Protective sheet: The protective sheet is a membrane-like component stretched by multiple airtight tubes. Gas is supplied from a gas source to the multiple airtight tubes, causing them to expand and the skeletal structure to rise. As a result, the protective sheet stretches and the protective membrane is deployed.

[0042] The portable animal protection device of the present invention does not employ an inflatable structure where the entire protective wall is made of airtight material; instead, only the airtight tube that forms the framework is inflated to deploy the protective sheet. With such a structure, a protective wall large enough to conceal the user's body can be instantly deployed with a small amount of gas.

[0043] Furthermore, the structure, which combines a protective sheet with an airtight tube framework, offers high resistance to attacks from wild animals such as bears. For example, when attacked by a bear's fangs or claws, the protective sheet deforms to conform to the attack, minimizing damage and preventing it from easily breaking. Also, even if a hole is made in the protective sheet, gas will leak out, preventing the protective wall from collapsing and maintaining its protective capabilities for a long time.

[0044] The protective sheet is made of a material whose surface is cut-resistant at least. Any material with sufficient strength to prevent attacks from wild animals without being easily torn can be used without particular limitations. For example, woven or nonwoven fabrics made of ultra-high molecular weight polyethylene fibers (UHMWPE, trade name "Dyneema," etc.) or aramid fibers (trade name "Kevlar," etc.) can be suitably used.

[0045] While there are no particular limitations on the evaluation criteria for cut resistance, the EN388 standard can be used, for example. The EN388 standard is a physical strength standard for work gloves, and it is preferable that its tear resistance (resistance to tearing) be 25N or higher (level 2), and more preferably 50N or higher (level 3). In this invention, "cut resistance" emphasizes "preventing the expansion of tearing after penetration" rather than "preventing penetration" by attacks with claws or teeth. Even if teeth or claws penetrate the protective sheet, if the protective sheet is not torn from that point, the protective barrier will not completely collapse, and the user's safety can be protected.

[0046] As long as they possess such properties, the type of material used for protective sheets is not limited, but examples include woven or nonwoven fabrics made from ultra-high molecular weight polyethylene fibers (UHMWPE) or aramid fibers. These materials are lightweight and have extremely high tensile strength and cut resistance, thus achieving both portability and protection.

[0047] Furthermore, it is preferable that the protective sheet has its surface coated or laminated with thermoplastic polyurethane (TPU). By applying such a surface treatment to the protective sheet, the tear strength of the protective sheet can be improved without significantly increasing the weight of the protective sheet. Specifically, by applying such a surface treatment, the slippage of the fabric fibers constituting the protective sheet can be suppressed and the progression of tears can be slowed, thereby improving the tear resistance of the protective sheet.

[0048] [2-5] Repellents: The portable animal protection device of the present invention preferably has an animal repellent pre-coated on the surface of the protective wall, or has a capsule containing an animal repellent attached to it, so that the animal repellent is released.

[0049] Examples of animal repellents include substances that cause animals to retreat through sensory stimulation, such as irritants and olfactory stimulants. Specifically, these include capsaicin, wood vinegar / bamboo vinegar, peppermint oil / menthol, etc. Among these, capsaicin is preferred because of its excellent immediate effect at close range and is also used as the main component of bear repellent sprays. These substances may be microencapsulated and applied to the surface of protective sheets, or sealed in containers that are destroyed by the pressure when the gas is released.

[0050] [2-6] Figures or colors used to intimidate animals: The portable animal protection device of the present invention preferably has animal-deterrent figures drawn on the surface of the protective wall, or animal-deterrent colors applied to it.

[0051] The shapes and colors used are not particularly limited, as long as they have an animal-intimidating effect. For example, an eye-like pattern (eye spot) that evokes a large predator is an effective shape. The dome-shaped protective wall instantly deploys, revealing a giant eye-like pattern that surprises wild animals and makes them hesitate to attack.

[0052] Furthermore, in terms of color, for example, warning colors combining black and yellow, or colors used by poisonous organisms in nature such as red and orange can be used. It is also preferable to enhance the visual deterrent effect by arranging holographic sheets or similar materials that scatter light.

[0053] [3] Specific embodiments: Below are two specific embodiments that employ the above configuration.

[0054] [3-1] First embodiment (dome type, handheld type): The first embodiment is a portable animal protection device 1 shown in Figures 1 to 4, in which a plurality of airtight tubes 6 extend radially from the center outward, and each airtight tube 6 extends in an arch shape to form an umbrella-rib-like framework, and a protective sheet 8 is stretched over the framework to deploy a dome-shaped protective wall.

[0055] This configuration consists of a protective sheet 8 that becomes dome-shaped when extended, and a plurality of airtight tubes 6 attached to its interior. The plurality of airtight tubes 6 are attached radially from the center outward, and when gas from a gas supply source is introduced, they expand and extend in an arch shape along the shape of the protective sheet 8, forming an umbrella-rib-like skeleton (the skeleton of the dome). Through this action, the protective sheet 8 is extended by the skeleton, and a dome-shaped protective wall is deployed.

[0056] In the first embodiment, a dome-shaped protective wall is deployed, so a method of installing a manifold 10 as shown in Figure 8 in the center of the protective sheet and introducing gas from the center side of the dome towards the outer edge of the dome using an airtight tube can be suitably used.

[0057] Furthermore, in the first embodiment, it is preferable that the dome-shaped protective wall has a viewing window 12 made of a transparent material in the central part. The transparent material is not particularly limited, but a material that combines transparency and strength can be suitably used. For example, it is preferable to make the viewing window out of polycarbonate or the like. By having a viewing window, the user can safely observe the behavior of animals from inside the protective wall.

[0058] Furthermore, in the first embodiment, it is preferable that a grip 14 for holding protective equipment is attached to the central part of the dome-shaped protective wall. The user can grasp this grip and hold the protective wall in front of them like a shield to block the charge of wild animals, or to crouch down and cover themselves with the dome to protect themselves, thereby fixing the protective wall in place.

[0059] In these configurations, it is preferable to have an opening in the center of the protective sheet where it makes contact with the dome, and to attach a ring-shaped mounting base made of a rigid material to this opening. By fixing a manifold, transparent window, grip, etc. to this mounting base, these components and the protective sheet can be integrated.

[0060] The material constituting the mounting base is not particularly limited as long as it is a rigid material with sufficient rigidity to withstand the use of protective equipment. For example, resin materials such as polycarbonate or metal materials such as aluminum can be used. The manifold, transparent window, grip, etc., are firmly integrated with the mounting base by bolting, welding, or other means.

[0061] The portable animal protection device 1 shown in Figures 1 to 4 embodies the first embodiment. The portable animal protection device 1 has eight airtight tubes 6 arranged radially from the center of the protective sheet 8. When gas is supplied, the airtight tubes 6 expand in an arch shape along the shape of the protective sheet 8, and a dome-shaped protective wall is instantly formed in about 0.5 to 1.5 seconds, like an umbrella opening.

[0062] [3-2] Second embodiment (pipe type / mounted type): The second embodiment is a portable animal protection device 31 shown in Figure 9, in which the plurality of airtight tubes extend in parallel in the vertical direction to form a cage-like framework, and a protective sheet 38 is stretched over the framework to deploy a pipe-shaped protective wall surrounding the user.

[0063] In this configuration, the portable animal protection device is attached to the user's waist by a belt or similar means. When deployed, multiple airtight tubes extend in parallel in the vertical direction, forming a cage-like structure. This creates a protective wall that envelops the user's entire upper body. Because this configuration deploys a protective wall that surrounds the user, it is possible to protect the user in a safer state compared to the first embodiment (dome-type / handheld type). [Examples]

[0064] Examples of the portable animal protection device of the present invention (the first embodiment described above) will be explained with reference to Figures 1 to 8 as appropriate. However, the portable animal protection device of the present invention encompasses all forms that satisfy the conditions described in the claims and is not limited to the following examples.

[0065] (1) Overall dimensions and shape: As shown in Figures 1 to 4, when the protective sheet 8 is deployed, it has a dome shape with a diameter of 1300 mm, a depth of 550 mm, and an arch length of 1000 mm from the center to the outer edge. As shown in Figure 6, the protective sheet 8 can also be rolled up towards the center and stored. In this case, it has a disc shape with a diameter of 360 mm and a thickness of 40 mm. The total weight, including the gas supply source, is approximately 1.0 kg.

[0066] (2) Composition of each part: (2-1) Airtight tube: The airtight tube 6 is made of 0.12 mm thick TPU laminated nylon (210-420 denier). Specifically, the TPU laminated nylon was formed into a highly airtight tubular shape by heat welding such as a high-frequency welder (RF welding). Its length is 850 mm, its inner diameter when expanded is 40 mm, and its internal volume is 1070 cc. Eight airtight tubes 6 are arranged radially from the center outwards. The airtight tubes 6 are integrally joined and fixed to the back side of the protective sheet 8 by heat welding or adhesive.

[0067] (2-2) Protective sheet: The protective sheet 8 was constructed using a composite nonwoven fabric containing ultra-high molecular weight polyethylene (UHMWPE) fibers. Specifically, it was made of Dyneema composite fabric: equivalent to DCF CT5K.18, with a basis weight of approximately 54 g / m². 2 A 20μm thick TPU coating was applied to prevent fiber misalignment and to ensure a strong bond with the airtight tube. The strength of this material meets the EN388 standard tear resistance level 2 (25N) or higher.

[0068] (2-3) Gas supply source: CO 2 A gas cartridge (filling amount 45g, gas volume approximately 25 liters at room temperature and pressure) was used. The volume of each airtight tube is approximately 1070cc (1.07 liters), and the total volume of 8 tubes is approximately 8.6 liters. The total amount of gas required, including the manifold and losses, is approximately 18 liters (at a pressurization of 0.08 MPa), which is sufficient to supply a sufficient amount of gas.

[0069] (2-4) Peephole: The viewing window 12 has an outer diameter of 200 mm (inner diameter of the visible area is approximately 170 mm) and is made of transparent polycarbonate.

[0070] (2-5) Manifold: Manifold 10 was made of rigid plastic and formed by CNC machining. The inner diameter of the central ring section was 8 mm, and the inner diameter of the gas outlet connecting to the airtight tube was 2 mm.

[0071] (3) Performance during use: A dome-shaped protective wall deploys 0.5 to 1.5 seconds after the trigger is pressed. Only the airtight tubes that form the framework are filled with gas, so even if it is struck by an impact such as a bear's blow, it will temporarily deform to release the force, and the internal pressure will immediately restore its shape. [Industrial applicability]

[0072] The portable animal protection device of the present invention is highly portable and can serve as a means of defense that instantly protects oneself when attacked by an animal. Therefore, it can be suitably used as protection against bears, which have been causing a sharp increase in damage in recent years. [Explanation of symbols]
